Just want to second Duckworth- amazing Montana made wool items. Their Vapor tee is my go to for everything.

And Imogene and Willie- currently wearing their Diana pleated jean. It was my first BIFL clothing item I ever bought and it feels worth every penny!

American Giant for their joggers and leggings.

Edit to add Raleigh Denim for their raw denim jeans.

And Bomba with the wool blend in particular have held up immensely well. The ones without wool I haven’t been as impressed with. They now make underwear too, hopefully with the same quality.
